MARINE

TRANSMISSIONS

INITIAL

OPERATION

All

HBW

marine

transmissions

are test-run

on

a test stand

with

the

engine

at

the

factory

prior

to

delivery.

For safety

reasons the

fluid

is

drained

before shipment.

Fill

the

gearbox with Automatic Transmission Fluid

(DEXTRON III). The

fluid

level should be

up

to

the index

mark

on

the dipstick.

To

check the

fluid

level, just insert the

dipstick,

do

not

screw

it

in.

Screw the dipstick into the case

after

the

fluid

level

is

checked

and tighten.

Do

not

forget the

sealing ring under the hexhead

of

the dipstick. Check for

leaks

and

make

a

visual

inspection

of

the coupling,

oil

cooler

and

hoses,

and shift

cables.

CHANGE

FLUID

Change the

fluid

for

the

first

time after about 25 hours

of

operation, then every 300 operating hours or at least once a

year or at winterizing.

Removing

the

fluid

Push a suction

pump

hose down through the dipstick hole

to

the bottom

of

the housing and suck out the

fluid.

(If

space

allows,

use the transmission drain). Remove the dralo plug

from the bottom

of

the transmission and allow the

fluid

to

dralo into a contalner, then reinstall the plug with its sealing

washer.

Wipe down

the

transmission and properly dispose of

the used

fluid.

After

running

the engine, shut down and

recheck the

fluid

level

OPERATING

TEMPERATURE

'rhe

·maximum

permissible

A'f.F

temperature should not exceed

230'

(110'). This temperature can.only

be

reached for a short

time.

A

CAUTION:

If

the.

transmission

fluid

temperature

is

too

high,

stop

the

engine

immediately

and

check

the

transmission

fluid.

LOCKING

THE

PROPELLER

Locking of

the

propeller shaft

by

an

additional brake

is

not

required:

use

the gear shift lever position opposite your direc-

tion of travel for

this

purpose. Never put the gear shift

in

the

position corresponding

to

the direction

of

travel of the boat.

WHEN

UNDER

SAIL

OR

BEING

TOWED

Rotation

of

the propeller without load, such as

when

the boat

is

being

sailed,

being

towed,

or anchored in a

river,

as

well as

operation of the engine

with

the

propeller stopped (for

charging the battery), will have

no

detrimental

effects

on

the

transmission

DAILY

OPERATION

o Check the transmission

fluid.

o

Visually

check the gear shift level linkage

and

transmission.

o Start

the

eugine in

neutral,

allowing a

few

minutes at

idle

to

warm

the

fluid.

o Shift into

gear.

NOTE:

Too

Iowan idle

speed

will

produce a

chattering

noise

from

the

transmission gear

and

damper plate.

In

such

cases

the

idle

speed

should

be

increased
